During the 1920s, Alphonse Capone was a notorious gangster who conducted his illegal enterprises in Chicago, Illinois. In 1929, the FBI was ordered by the Attorney General to investigate the legitimacy of an affidavit that petitioned for a postponement of Mr. Capone's appearance in response to a Federal Grand Jury subpoena. The investigation established that facts within the affidavit were indeed false. On February 25, 1931, Mr. Capone was tried and convicted of contempt of court. When Mr. Capone was convicted for income tax evasion, the Judge ruled that the sentence for contempt of court should be served concurrently with the tax evasion sentence.
